Wireless (sort of) Speaker Mount
Running wires to the rear speakers of a 5.1 or 7.1 system is always problematic. Several companies demonstrated wireless add-on devices, but the Link-Mount is the most unusual and clever solution I’ve seen so far. The wireless receiver/amp is built into a universal speaker wall bracket. A DC power cord is then run through the wall to a termination plate where you connect the wire to a transformer plugged into an electrical outlet. Since it’s DC running through the wall, no electrician is necessary. Pricing is in the $400 range for a pair of brackets and a transmitter.
